Today's lecture focuses on the history of urban transportation. In the early 20th century, most cities relied on trams and buses. However, with the rise of private cars in the 1950s, many tram networks were dismantled. Interestingly, some cities like Melbourne chose to keep their trams, which are now seen as a cultural icon. In contrast, cities that removed trams often face traffic congestion today. The lecture also mentions that cycling infrastructure was largely ignored until the 1990s, when environmental concerns prompted a shift. Now, many urban planners advocate for a mix of transport modes to reduce carbon emissions.
